Mandevilla plant named ‘Lanvirginia’

ABSTRACT

A new and distinct cultivar of  Mandevilla  plant named ‘Lanvirginia’, characterized by its upright and twining plant habit; moderately vigorous to vigorous growth habit; glossy dark green-colored leaves; freely flowering habit; and pink-colored flowers with red purple-colored centers.

Botanical designation: Mandevilla×amabilis×Mandevilla boliviensis.

Cultivar denomination: ‘LANVIRGINIA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mandevilla plant, botanically known as Mandevilla×amabilis×Mandevilla boliviensis and hereinafter referred to by the name ‘Lanvirginia’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Malause, France. The objective of the breeding program is to create new Mandevilla plants with good plant habit and numerous attractive flowers.

The new Mandevilla plant originated from a cross-pollination conducted by the Inventor in Malause, France in 2009 of Mandevill×amabilis×Mandevilla boliviensis ‘Sunmandeho’, disclosed in U.S. Plant Pat. No. 11,556, as the female, or seed, parent with a proprietary selection of Mandevilla×amabilis×Mandevilla boliviensis identified as code number Si-06-850-12, not patented, as the male, or pollen, parent. The new Mandevilla plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Malause, France in 2013.

Asexual reproduction of the new Mandevilla plant by cuttings in a controlled greenhouse environment in Malause, France, since 2014 has shown that the unique features of this new Mandevilla plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Lanvirginia’. These characteristics in combination distinguish ‘Lanvirginia’ as a new and distinct Mandevilla plant:

-   -   1. Upright and twining plant habit.     -   2. Moderately vigorous growth habit.     -   3. Glossy dark green-colored leaves.     -   4. Freely flowering habit.     -   5. Pink-colored flowers with red purple-colored centers.

Plants of the new Mandevilla can be compared to plants of the female parent, ‘Sunmandeho’. Plants of the new Mandevilla differ primarily from plants of ‘Sunmandeho’ in plant habit as plants of ‘Sunmandeho’ have a climbing type habit whereas plants of the new Mandevilla do not have a climbing type habit. In addition, plants of the new Mandevilla and ‘Sunmandeho’ differ in flower color as plants of ‘Sunmandeho’ have yellowish white-colored flowers.

Plants of the new Mandevilla can be compared to plants of the male parent selection. Plants of the new Mandevilla differ primarily from plants of the male parent selection in flower color as plants of the male parent selection have lighter pink-colored flowers.

Plants of the new Mandevilla can also be compared to plants of Mandevilla sanderi ‘Lansouthcarolina’, disclosed in U.S. Plant Pat. No. 26,406. In side-by-side comparisons conducted in Malause, France, plants of the new Mandevilla differed primarily from plants ‘Lansouthcarolina’ in flower color as plants of ‘Lansouthcarolina’ have lighter pink-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Mandevilla plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Mandevilla plant.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Lanvirginia’ grown in a container.

The photograph on the second sheet is a close-up view of a typical flower of ‘Lanvirginia’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the spring and early summer in 17-cm containers in polyethylene-covered greenhouse in Malause, France and under cultural practices typical of commercial Mandevilla production. During the production of the plants, day temperatures ranged from 15° C. to 26° C. and night temperatures ranged from 14° C. to 15° C. Plants were six months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
